Be it known that I, GUY C. HANNA, a citi-V zen of the United States, and a resident of Plainfield, in the county of Hendricks and State of Indiana, have invented a new and useful Improx'fement in Pneumatically-Tired Wheels, of whichtthe following is a specilication.

My present invention relates generally to pneumatically tired wheels, and more par ticularly to a combined tire and rim construction, the parts of which coperate in such manner as to minimize the usual danger of puncture and provide means by which the tire may be protected in deflated condition and by which. the wheel may remain in use without (lange-ref pinching 01 split-- ting the tire as at present.V

In the accompanying drawings illustrat-V ing several constructions by which my ink r ventionmay be carried'out and which form a part of thisspecifieation,

lIVigure 1 is a radial section through a rim and tire construction embodying my invention,

Fig. 2 is a similar view through a slightly modified form,

Fig. ElV is a similar view through' another mod ified form,

` Fig. 1 is a partial side elevation of the 4form of my invention illustratedlin Eig, 3,

Fig. 5 is a view similar toV Figs. 1 to 3r inclusive, illustrating another modified form, and k Figs. 6 and i( are similar'viewsillustratingv still other modified forms.

Referring now to Fig. l'my invention' contemplates the use of a rim 10 of suitable construction, carrying side plates 11, each of which extendsannularly around the entire circumference of the rim and pro3ects ma- 4 terially therebeyond in an outward direction, the plates 11 beingin spaced relation to receive therebetween the tire including an inner inflatable tube 12 and a shoe 13, the latter of which is provided with a central annular enlargementV 14 normally projecting exteriorly between the outer edges of the rim plates 11, and is of solidconstruction with or without internal reinforcements inthe nature of embedded rings `15.

'I he tube 12 of the tire is confined between the side plates 11 and between the as normal, V(iperates to hold the shoe 13 in tween which the proj ecting portion 14 of the l shoe 13 is movable when tl' tube 12 is deflated, which form the traetive surface of the wheel.

The shoe 13 of the tire and the outer por tions of the side plates 1.1,are preferably provided with internally engaging ribs 17 and 18 which eiig'age. when thetuhe 12 .is inflated, to prevent the tube from blowing out between the shoe 13 and side plates 11, due to theinternal pressure of the inflated tube 12 laterally against, the said side plates 11. f

As seen in Fig. 1 the side plates 11 have inner annulaiflanges 19 at the sides of the rim 10, providing for connection of the side plates to the rim 10 by bolts 20 extending laterally Athrough the rim at spaced points therearound vand at the same time providing for ready removal of one of the side plates 11.` in order that access may be had to the tube 12 for purposes of repair or substitution.

As seen in Fig. 2 however, in which the ,tire including its tube 12 and shoe 13 with its exteriorly projecting portion 14 are similar to the same parts in Fig.1, the side plates 11a are formed integral with one another, their integral connecting portion 21 being secured to the periphery of the rim 10 by means of suitable fastening members 22.

'As seen in Fig. 3, the side plates 11b are reinforced at their outer edges by annular rings 23 around said edges, in case the side plates are made of any material other than that capable of holding them 'rigid in case of deflation of the tire, the supplemental rings 23 being integral with annular rings 24 by means of spaced connecting webs 25 the rings 24 being arranged along the outer aces of the inner flanges 19* of the side plates, and the connecting webs 25 extending radially fromthe inner rings 24: to the outer rings 23, as best seen byrefereuee t0 Fig. 4.

As seen in Fig. 5, the side plates 11e, with inner flanges 19h, connected o the sides` of the rim 10 bythe bolts 20. receire a shoe 1'3,

.of the invention shown in Figs. 1 to 4 in- In Fig. 6 the side plates 11d are straight, the inner portions thereof being bolted by the bolts 2O to the rim 10 and the outer portions of which are in spaced parallel relation to receive between the inner portions thereof an inflatable tube 12" and a shoe '13, the peripheral portion 14". of which projects-beyond the extreme outer edges of the plates 11.i so as to normally form the tractive surface.

In the form of the invention shown in Fig. 7 the construction is similar to that of Fig. 6, except that the straight side plates 11e are inclined toward one another in an outward direction and their outer edges are inturned so that they not only form the trac tive surface when the inner tube 12 is deilatcd, but also provide inturned edges'Q? engaging the ribs 28 of theshoe 13 when the tube 12 is inflated, so as to prevent danger of blowouts, substantially as do the vclencher ribs 17 and 18 of the forms of the invention seen in Figs'. 1 to 4 inclusive'.

It is obvious, however, and in accordance with any of the preceding forms, the pneu- -matictire when deflated is protected against pinching and splitting during what is known as riding on the rim at the present time, by virtue of the outer portions of the side plates, the outer ed es of which` form the traction surface of t e wheel when the tire is deflated.

' It is -likewise obvious that with my improved construction the pneumatic tire or rather the inflatable tube thereof, is effec` tively protected .from blowouts and punc-y tures as well as `from side abrasions'against curbing, nearby. vehicles and other obstructions engaging the side of the wheel.

ortion 14 of which projects between I claim Y l 1.v In a device of the character described, the combination of the wheel rim, spacedr side members secured to and extending around the rim, each of which is of. integral formation and consists of inner and outer annular rings and radial connecting webs of which the inner ring is secured to said rim, with open spaces between the' webs around and between said rings, and a pneu.

members including a portion normally projecting exteriorlybeyond the outer rings of the said side -members to cushion the wheel, said tire being movable inwardly beyond s aid outer rings in use when the tire is deflated, the outer rings of the said side members forming the traction surface of the wheel when the tire is deflated and the said exteriorly ,projecting portion of the tire moves inwardly beyond said rings.

In a device of the character described, the combination with a wheel rim, spaced side pieces secured to and extending Varound the rim, each having inwardly extending annular tire engaging means around the outer edge thereof, apneumatic tire around the rim between the said side pieces and 4inside members, said outer rings -of said sideo pieces forming the traction surface of the wheel when the tire is deflated andits said projecting portion moves inwardly of the.A side pieces.
